As a result of all these important functions, carbohydrate biochemistry is involved in a large number of disease states. Although multiple carbohydrates exist, only a few sugar molecules and polysaccharides are important to human physiology (e.g. only eight different carbohydrates are found as constituents of glycoproteins and glycolipids). However, a number of additional molecules created by linkages of carbohydrates to proteins play various roles in cell–cell interactions and biological structures.
